Resumen
Con el uso generalizado de las técnicas satelitales aplicadas en topografía y geodesia, se ha generado la necesidad de transformar entre marcos coordenados de referencia globales y locales. En este artículo se describen y comparan los métodos más aplicados para la transformación de coordenadas entre datums geodésicos, tales como: la transformación de siete parámetros, la regresión múltiple y la transformación de Molodensky. Se proveen las ecuaciones fundamentales de transformación y su implementación en lenguaje MatLab.
With the generalized use of satellite techniques and their applications in land surveying and geodesy, a necessity to transform between global and local reference frames has been seen. In this article, a description and comparison of the most common methods for coordinate transformation between geodetic datums is given. Different approaches such as the seven parameter transformation (Bursa-Wolf method), multiple regression, and Molodensky’s transformation are explained among other. Fundamental transformation equations as well as MatLab code for their implementation is provided.
